2. SAFETY REGULATIONS AND INFORMATION
Carefully read these operating instructions before beginning work on the
device and before each use. Observe the safety regulations to prevent
malfunctions or danger to persons. These operating instructions are to be
regarded as part of the device. Store the instructions - in the vicinity of
the product - so that they are accessible to the users at all times. The
device is only to be sold or passed on together with the operating
instructions. The operating instructions must be accessible to the
operating and maintenance staff. These operating instructions may be
duplicated and distributed to inform about potential dangers and their
prevention.
2.1 Hazard levels for warnings
These operating instructions use the following hazard levels to indicate
potentially hazardous situations and important safety regulations:
DANGER
Indicates an imminently hazardous situation which will result in
death or serious injury if the specified actions are not taken.
Compliance with the instructions is imperative.
WARNING
Indicates a potentially hazardous situation which can result in
death or serious injury if the specified actions are not taken.
Exercise extreme caution while working.
CAUTION
Indicates a potentially hazardous situation which can result in
minor or moderate injury or damage to property if the specified
actions are not taken.
NOTE
A potentially harmful situation can occur and, if not avoided, can
lead to property damage.
2.2 Staff qualifications
Only electricians qualified in electrical explosion protection may install
the device, perform the test run and work on the electrical system. The
device may only be unpacked, serviced, turned on or off, set, used,
operated, disassembled, transported or otherwise used by suitably
qualified, properly instructed and authorized technical staff.
2.3 Basic safety rules
Before using the device always perform hazard assessment in line with
the order on operating safety (BetrSichV). The safety hazards associated
with the device must be assessed again following installation in the final
product.
Note the following when working on the device:
;
Malfunctions and defects that affect safety must always be corrected
immediately.
;
The device is only to be used in technically proper working order, for
the intended purpose, in a safe manner, with attention to potential
dangers and in accordance with the operating instructions.
;
No modifications, additions or conversions are to be made to the
device (for example changes to the guard grille or the attachment of
other devices to the fan housing) without the approval of ebm-papst.
;
Modifications to the device result in loss of Ex approval. ebm-papst
Mulfingen GmbH & Co. KG accepts no liability for damage resulting
from such modifications.
2.4 Voltage
;
Check the electrical equipment of the device at regular intervals; see
Chapter 7.2 Safety inspection.
;
Replace loose connections and defective cables immediately.
DANGER
Live terminals and connections even with device
switched off
Electric shock, inadvertent triggering of an ignition spark and
capacitive residual voltage can cause an ignition spark in the
event of a short circuit.
→ Before disconnecting the wires in the terminal box,
short circuit the wires (L1, L2, L3) and PE outside the
explosion hazard area, see Chapter 5.8.2 Switching off
the device for maintenance.
→ Wait five minutes after disconnecting the voltage at
all poles before opening the terminal box
CAUTION
In the event of a fault, the rotor and the impeller will be
energized
The rotor and the impeller have basic insulation.
→ Do not touch the rotor and impeller once installed.
CAUTION
If control voltage or a stored speed set value is applied,
the motor will restart automatically, e.g. after a power
failure.
Risk of injury
→ Keep out of the device danger zone.
→ When working on the device, switch off the line voltage
and ensure that it cannot be switched back on.
→ After working on the device, remove any tools or other
objects from the device.
2.5 Safety and protective features
DANGER
Protective device missing and protective device not
functioning
Without a protective device there is a risk of serious injury, for
instance if the hands reach or are sucked into the device during
operation.
→ Operate the device only with a fixed protective device and
guard grille.
→ The fixed protective device must be able to withstand the
kinetic energy of a fan blade that becomes detached at
maximum speed. There must not be any gaps which it is
possible to reach into with the fingers, for example.
→ The device is a built-in component. As the operator, you
are responsible for ensuring that the device is secured
adequately.
→ Stop the device immediately if you notice a missing or
ineffective protective device.
